Logout from Customer Account API

What it does:

• Deletes stored access and refresh tokens
• Initiates Shopify’s end session flow (if tokens available)
• Redirects to return URL or back to customer portal

Two scenarios:

1. App-initiated logout: Customer clicks logout in portal

   • Portal calls this endpoint with return URL
   • Tokens deleted, redirects to Shopify end session endpoint
   • Shopify redirects back to return URL

2. Shopify-initiated logout: Customer logs out globally from Shopify

   • Shopify calls this endpoint with id_token_hint
   • Tokens deleted, returns success

Important:

• This only logs out from Customer Account API, not from Shopify customer account
• Customer will need to re-authenticate to use Customer Account API features again
• Does not affect regular customer portal access (subscription management)

Authentication: Optional - can be called from Shopify without authentication
